Final answer:
The 2022 Maxima's available Rear Cross Traffic Alert (RCTA) system uses radar-based sensors to detect vehicles approaching from either side when backing up, notifying the driver with audible and visual warnings to prevent collisions.
Step-by-step explanation:
The 2022 Maxima's available Rear Cross Traffic Alert (RCTA) system uses sensors located around the vehicle to detect traffic that may not be visible directly to the driver when backing up. These sensors are typically radar-based and monitor the areas behind and to the sides of the vehicle while it is in reverse. If the system detects an approaching vehicle from either side, it can notify the driver through a series of audible and visual warnings. The warnings include beeps or chimes and warning messages or lights on the vehicle's dashboard or rearview mirror, alerting the driver to potential hazards. This can greatly assist in avoiding collisions with cross traffic in places such as parking lots, where visibility is limited.
